Adaptive non-dispersive and direction-dependent attenuation of artifacts in seismic wave propagation

A non-transitory computer-readable medium comprising computer-executable instructions stored thereon that, when executed on a processor, cause the processor to perform:

• obtaining seismic data associated with a subsurface region of interest, wherein the seismic data comprises a plurality of time-space waveforms;
• determining a plurality of mechanical parameters corresponding to a formation of the subsurface region of interest based, at least in part, on the plurality of time-space waveforms;
• generating a filtering region based on an artifact identified in the plurality of time-space waveforms;
• determining a plurality of attenuation parameters based, at least in part, on the filtering region, the plurality of attenuation parameters being configured to attenuate the artifact;
• filtering the plurality of time-space waveforms based, at least in part, on the plurality of mechanical parameters and the plurality of attenuation parameters to generate a plurality of filtered time-space waveforms;
• generating a seismic image of the subsurface region of interest using the plurality of filtered time-space waveforms;
